In the industrial pipeline system, DIN Standard Gate Valve, known for its high precision, stability, and strong pressure resistance, is widely used in Europe and global high-end engineering projects. As a leading valve manufacturer in China, Zhongguan Valves has deeply integrated German industrial standards with advanced domestic manufacturing technology and launched a full range of DIN gate valves. These products have been highly recognized by users in electric power, petrochemical, shipbuilding, metallurgy and water treatment industries.
Product Highlights and Key Procurement Data
Our DIN gate valves adopt a precision-machined wedge design and full-bore flow channel, ensuring low flow resistance and extremely reliable sealing performance. The sealing pair can be configured with materials such as F304, F316, 410, Stellite or bronze, meeting different working conditions from normal fluid transport to high-temperature and corrosive media.
High-performance sealing system
The valve body and bonnet are processed strictly in accordance with DIN EN 1983, DIN 3352 and other standards. The sealing surface of the wedge is treated with advanced alloy welding technology, ensuring a long service life and excellent abrasion resistance.
Actual factory test results show that the sealing performance is stable under -40℃ to 450℃, and the leakage rate is controlled at ≤0.01%, which is much stricter than the standard requirement.
Strict quality control
Each valve must undergo more than 20 procedures of inspection, including hydrostatic test, nitrogen leak test, high-temp simulation test and material PMI verification, ensuring full compliance with EN12266-1, DIN 3202, DIN 2501.
Third-party sampling inspections in the past five years have maintained a 100% pass rate, proving the consistency and stability of Zhongguan Valves’ manufacturing system.
Strong production capacity & customization service
Our factory has mature production lines and advanced CNC equipment, with a monthly capacity of over 100,000 units.
We can provide rapid delivery for standard DIN models and offer flexible customization for:
Special materials (e.g., Duplex Steel, Hastelloy C276)
Non-standard face-to-face dimensions
Low-temperature versions
Fire-safe requirements
These advantages make Zhongguan’s DIN gate valves the preferred choice for buyers seeking a balance of quality, durability and cost-effectiveness.
1. For which working conditions are DIN standard gate valves applicable? Why do engineering projects all require DIN?
The products are mainly used for:
Municipal water supply and pipeline systems
Building fire protection systems
Industrial circulating water
Hot and cold water systems
Some steam and light chemical media
The reason why many European and Middle Eastern projects specify the DIN standard is as follows:
The flange dimensions are uniform and easy to install.
The sealing requirements are strict.
The product has a longer lifespan.
The maintenance cost is low.
The DIN gate valves we provide to customers have undergone strict pressure tests and are reliable for long-term operation. This is why many projects are willing to purchase them repeatedly.
2. What is the maximum range of your DN? And how long is the delivery time?
We routinely produce DIN standard gate valves ranging from DN50 to DN600. Among them, the sizes of DN80 to DN300 have the largest inventory.
For larger diameters, we can customize according to orders.
Regarding the delivery time:
For regular models, it takes 5 to 12 days.
For special materials or sizes, it takes 15 to 28 days.
We have production bases in both Tianjin and Wenzhou, which enables us to flexibly adjust production capacity and ensure the delivery time of projects.
3. Will the gate valve leak? How do you ensure a reliable seal?
The most crucial aspect of a gate valve is its sealing performance. Therefore, we have very strict requirements for the sealing part.
Each valve undergoes 100% shell and seal tests before leaving the factory.
The sealing material can be replaced according to the medium (EPDM, NBR or heat-resistant material)
The valve plate guide rails have been precisely machined, making the opening and closing process smoother and preventing any jamming.
The valve stem is made of stainless steel, which is corrosion-resistant and does not tend to bend.
There are numerous cases where customers have reported zero leakage after using the product for a long period of 2 to 5 years.
4. How do you ensure the lifespan of the gate valve?
The lifespan is not only determined by the material, but also by the craftsmanship. We mainly ensure the lifespan through the following aspects:
The valve body has sufficient wall thickness and excellent pressure resistance.
The valve stem is made of corrosion-resistant stainless steel.
The valve plate is evenly coated with rubber, ensuring the longevity of the seal.
The inner cavity coating thickness meets the standard and has higher corrosion resistance.
Precision processing equipment maintains structural stability.
Therefore, our DIN gate valves have consistently performed well in municipal pipelines and building systems over an extended period of time.
